I always used the trip-0-meter. But inaccurate speedo's really get my goat and I don't think I ever had an accurate speedo on a bike except for a BMW K75 and a few later model Harleys, most are 3% to 5% optimistic.
They are all a little different. I ran a Chevy S10 plum out of gas at 3 am in the morning on I75 out in the middle of nowhere when the gauge showed I had 1/8 of a tank. That was fun.
Hard to go wrong keeping a sensible odometer reading.

When I was preparing my CB to be shipped to Hawaii by running all the gas out of it, the Guage said it had 22 miles of fuel left in it and the tank was dry, good thing it was already in my garage. Although I think the Guage gets smarter with time, I recently refilled the tank with a little over 3 gallons with a reading of 30 miles left in the tank, so I guess all things considered this guage is better than my no guage Triumph, but it pails in comparison to my very exact Sport Touring Triumph I used to have #deepregrets.

UPDATE: As of lately, I think my fuel guage has indeed gotten quite a bit more accurate. That's good news I think. I guess about 6 thousand miles will do it!

My CB1100 speedo is the most accurate one I have had on a bike. Reads 1 mph fast over numerous gps checks. Gas gauge, not so much. I also use the odometer every time I gas up.

My triumph thruxton had no gauge. Just a small light. The light was useless as it usually would only come on when you had "oh sh*t" miles left.

I just filled up with 2.864 gallons when my last fuel gauge segment started flashing. Supposedly, I still had about one gallon left in the tank. I got very close to 130 miles on that last tank, so my mileage calculation was 45.4 mpg. That is reasonably good fuel gauge accuracy, but like most of you, I ALWAYS reset my trip odometer at every fill up as a "backup" to the fuel gauge.
Btw, I also reset my other trip odometer every time I lubricate the chain to help me remember when that should be done again, which I typically do about every 250 miles.

I lube my chain every 300 miles or so!

Same issue on my 1150RT BMW. My solution was to use in trip odometer. At 200 mile I would fill it up. With the CB1100 I use 100 miles.

Hey, you guys want to know how to get 79 mpg? Do what I do--forgot to reset the mileage on the "A" button trip meter. :-)
I was at 204 miles and still had a quarter tank gas left. My "miles left" light had not come on. Usually fill up around 140 miles whether the light is lit or not.
